Kosh I is a bigot who plays race favorites.
(I don't think what I have to say will spoil
The above statement stems from a question that has been eating away a back corner of my mind for sometime:
Why does Kosh intervene with G'Kar and never with Londo?
I don't buy that the answer is simply that Londo is "too far gone" to be receptive to the message. And a major reason I don't is Emperor Turhan's encounter with Kosh in The Coming of Shadows.
Consider what Emperor Turhan represents. He is the reformer, the man seeking peace, the man trying to turn the tide in his society and do something to atone for the mistakes of his world's history. He risks his health and, as we ultimately see, his very life to reach out a hand to his enemy. If anyone deserves to see a Vorlon sans encounter suit, it is he.
Yet when Kosh visits Turhan on his death bed, he remains shrouded. Why? Why, when beings of practically every other race are given the opportunity to see Kosh later that year, is this Centauri, who represents everything that is noble in sentient life, denied that experience? I realize they were in the Med-Lab, which is a public place, but couldn't Kosh have just cracked open the helmet a little? Or ordered everyone in the room to leave? Or entered Turhan's mind as he did with G'Kar? Or something?
Until someone comes up with a better answer, I can only conclude that Turhan is being punished for the sins of his fathers- that the Vorlons have decided that all Centauri, no matter who they are, are not worthy of their presence...
...even though I can name other Centauri besides Turhan who are in fact worthy.
